Definitions

  • the invention relates to a securing device for objects joined together by means of elastic adhesives that adhere to one another.
  • Adhesive connections between objects are occasionally additionally secured to support liability and / or to secure them, for example by simultaneously screwing or riveting the objects.
  • the object of the present invention is to secure elastic bonds between two objects in such a way that the elasticity of the adhesive is retained, but that the objects remain connected to one another if the adhesive fails.
  • a first object has a first adhesive surface and a second object has a second adhesive surface and the adhesive surfaces face each other and an adhesive is arranged between the adhesive surfaces and the first object has one or more recesses in the region of the first adhesive surface and the second object in the area of the second adhesive surface and pin-like elements extending through the recesses of the first object and the cross section of the recesses of the first object is larger than the cross section of the pin-like elements and that the pin-like elements are fixed in the second object and have an enlarged cross section above the first element, which is larger than the cross section of the respective recess.
  • the invention is not critical with regard to the objects used.
  • the securing device according to the present invention is preferably used on metal sheets or plates or on profiles or supports.
  • the objects can be made of metal, such as ferrous or non-ferrous metals, of plastics or of metal-plastic composites.
  • the metals can be steel, iron, galvanized iron or aluminum or their alloys.
  • plastics polyvinyl chlorides, polyamides or polyesters etc.
  • the plastic objects can be reinforced by means of fibers, optionally in the form of woven fabrics, knitted fabrics or nonwovens made of inorganic or organic materials. Examples of this are glass fiber, aramid fiber or carbon fiber reinforced plastics.
  • Metal-plastic composites can be composite or laminated materials, for example made of a plastic core and metallic cover layers or a metal core and plastic cover layers.
  • Sheets and plates or supports and profiles made of aluminum or its alloys are preferred, wherein the supports and profiles can also be extruded.
  • the profiles can also be hollow chamber profiles.
  • the adhesive is expediently an adhesive tape.
  • the adhesive tape can have a carrier, such as a plastic carrier, and an adhesive on both sides of the plastic carrier, and can thus be an adhesive tape that is adhesive on both sides or on both sides.
  • the adhesive tape can also be a foam fabric, knitted fabric or fleece, for example made of natural or artificial fibers, which is impregnated with an adhesive and which is an adhesive tape which is adhesive on both sides or on both sides.
  • the adhesive can also be used as such e.g. can be applied in liquid to pasty form or as foam by brushing, knife coating, spraying etc.
  • Adhesives based on physically setting adhesives such as hot melt adhesives, for example styrene-butadiene, polyamide, ethylene vinyl acetate and polyester adhesives, are advantageous; Plastisol adhesives, eg PVC with plasticizers and adhesion promoters; Pressure sensitive adhesives, for example rubbers or polyacrylates; Contact adhesives, for example polyurethane-styrene-butadiene or polychloroplene adhesives; Solvents / dispersion adhesives; e.g.
  • polyurethane vinyl acetate, vinyl chloride, Vinylidene chloride copolymers or chemically setting adhesives, such as, for example, reactive adhesives of the epoxy plus acid anhydride type, epoxy plus polyamines, polyisocyonates plus polyols, cyanoacrylates, metacrylates, UP with styrene or metacrylates, PF plus PVFM or NBR, PJ or polybenzimidazoles with the proviso that such adhesives show elastic behavior when hardening or setting or sticking.
  • adhesives such as, for example, reactive adhesives of the epoxy plus acid anhydride type, epoxy plus polyamines, polyisocyonates plus polyols, cyanoacrylates, metacrylates, UP with styrene or metacrylates, PF plus PVFM or NBR, PJ or polybenzimidazoles with the proviso that such adhesives show elastic behavior when hardening or setting or sticking.
  • Double-sided adhesive tapes e.g. in the form of foamed acrylic adhesives.
  • the thickness of the adhesive between the objects can be, for example, from 0.2 mm to 3.0 mm, preferably from 0.5 mm to 1.0 mm.
  • the first object has recesses in the area of its adhesive surface.
  • Such recesses can be, for example, angular or round cross-section and generally run through the object in a vertical axis.
  • the recesses can be polygonal, for example triangular, square or hexagonal and are preferably round, i.e. they are holes.
  • the holes are generally cylindrical.
  • the bores can also be truncated pyramids or countersunk on the side opposite the adhesive surface.
  • the pin-like elements can be, for example, screws, rivets, pins or bolts, and self-drilling screws or expanding rivets are preferred.
  • the pen-like elements are defined in the second subject.
  • the pin-like elements can, for example, be glued, welded, but preferably screwed, screwed, pressed or riveted onto the second object.
  • the pin-like elements have an enlarged cross section above the first element, which is larger than the cross section of the respective recess.
  • the expanded cross section can be, for example, a screw head, a rivet head, a bolt head, etc.
  • the cross-sectional area of the pin-like elements in the region of the recess is preferably 5 to 30% smaller than the cross-sectional area of the recess itself.
  • the pin-like elements can for example consist of plastic or metal.
  • the pin-like elements made of plastic or metal the objects are made of metal, the pin-like elements are also expediently made of metal, for example made of steel, iron, non-ferrous metal or aluminum or its alloys.
  • the cross-sectional area of the expanded cross-section of the pin-shaped element is preferably 50 to 200% larger than the cross-sectional area of the respective recess in the first element.
  • the expanded cross section of the pin-like element i.e. the screw head, the rivet head, the bolt head, etc. directly adjoins the second object or at least touches the second object or is up to 0.5 mm away from it.
  • An adhesive connection containing the present securing device can be applied, for example, in such a way that on the first object or on the second object or on both objects simultaneously or alternately, accordingly for example on metal plates or on metal profiles, on the side intended for the adhesive, for example the adhesive tape, is attached.
  • the first object can be provided with a number of recesses, for example bores, beforehand or subsequently. It is advisable to have 10 to 50 holes per square meter of adhesive surface or 3 to 10 holes per linear meter over the length.
  • the second object for example also a profile or a sheet metal, is brought into contact with the surface intended as an adhesive surface with the first object and, depending on the type of adhesive, optionally pressed or heated or pressed with heating.
  • recesses are made in the second object through the recesses of the first object.
  • the pin-like elements are introduced and fixed in these recesses in the second object. This can be done, for example, by screwing in, riveting or spreading.
  • the pin-like elements are self-drilling screws or the like, there is no need to make recesses on the second object.
  • Passing through the recess in the first object are self-drilling pin-like elements on the second object fixed.
  • the pin-like elements are inserted so deeply with respect to the first object that the underside of the enlarged cross section of the pin-like element touches the surface of the first object, possibly under slight pressure or is slightly protruding above the first object.
  • the first object can alternately have recesses and pin-like elements and, correspondingly, the second object can also alternately have recesses and pin-like elements which are arranged alternately or in groups.
  • Figure 1 shows an example of the connection of two metal sheets, and the arrangement of the securing device in cross section.
  • a first object 1 in the present case a metal sheet, and the second object 2, also a metal sheet in the present case, are adhesively bonded to one another via an adhesive 9, for example in the form of an adhesive tape.
  • the first object 1 has, for example, the recesses 3 and 4 in the form of cylindrical bores.
  • Fixed in the second object 2 is a rivet 5 which has been inserted into a predrilled opening in the object 2, 5 expansions leading to a secure hold in the shaft part 8 of the rivet.
  • the rivet head 10 laterally projects beyond the recess and is at a short distance from the first object 1, while the bore 3 has a larger cross section than the rivet body 5.
  • a self-drilling screw 6 is guided through a bore 4 and its thread 7 is screwed into the object 2.
  • the head 11 of the self-drilling screw 6 lies lightly on the first object. With the head 11, the bore 4 and an area of the first object is covered. This means that the first object 1 and the second object 2 can move against each other to a small extent in the horizontal direction, but that vertical movement is essentially impossible.
  • the first object can be supported against the second object via the securing device in the form of one or a plurality of pin-like elements.
  • the securing device in the form of one or a plurality of pin-like elements.
  • Typical strengths of bonds are, for example, a tensile strength of 1 to 5 N / mm2, a tensile shear strength of 1 to 5 N / mm2 and a peel strength of 0.2 to 1 N / mm2.
  • Present security device is particularly suitable for use in connecting a first item e.g. a sheet or profile and a second object
  • the second object e.g. is a hollow profile, and preferably the pin-shaped element, preferably blind.
  • the pin-shaped element is in particular a self-drilling screw or an expanding rivet. This has the advantage that when the securing device is released, no parts fall into the hollow profile and remain there. This is of great importance if the present securing device is used on the adhesive connections of profiles and sheets that are used for constructions in body construction, for example for railway cars, buses, travel cars or trucks.
